CAP-HEMMING MACHINE.

To'aZZ whom it may concern Be it knownthat we, GEZA HoRvATHand GREEN, citizens of the United States, residing at Wheeling, county. of Ohio, State of l/Vest Virginia, have invented certain new and useful Improvements in-Gap-Hemming Machinespof which the following is a specification, reference being. This invention relates toa capjhemming machine and particularly .to an apparatus for applying a ring of solder to the pe- .riphery of a cancap.

The invention has for an object to provide a novel and improved construction of machine by which a ring of solder is' cut from a stripthereof and partially bent, the can cap fed and deposited within this ring which is applied or partially secured thereto, and subsequently fully securing the solder ring at the peripherytof the cap and delivering the completed article, these several operations being so timed as to .pro-

duce an automatic and continuous operation of the machine.

, A further object of the invention is to provide animproved construction fdrcutting or punching the rings of. solder of successively different sizes, such rings being other to. effect the economical use of the solder and rapid operation of the machine to caps .of different sizes. Other and further: objects and 'advanthe invention will be hereinafter fined by the appended claims.

for feeding a strippr ribbon'of solder and clamping it inposition, means for cutting rings from said solder and means for'feeding a series of caps to these rings and depositing them therein, means for applying or partially securing the ring tot-he periphery of the cap, means for com pletely securing a ring to the livering the completed article, and means for automatically andcontinuously effecting the several operations.

Thenumeral 25 indicates the solder strip or ribbon which is fed .in a guide groove or way 26 (Fig. 7). This feeding is effected This machine'comprises essentially, means cap and de y by a slide 27 mounted in the way 26 and carrying a clamping plate 28 as shown in Figs. 7 and 8 which is guided therein for sliding movement. The slide .27 is provided with the standards 29 which form a bearing fora rock shaft 31 which is preferably angular in cross-section and has slidingly mounted thereon a cam 30 cooperating with The rock shafti l is actuated by a strip;

33 which is" connected as herecrank arm inafter described for intermittent moves.

This clamp com-- .a block 32 upon the plate 28 to force said plate into gripping contact with the solder i which is guided in its vertical movement by posts 38 extending through the standards and provided above said standards with tension springs 39 secured to the posts and bearing upon the standards to lift the plate 37 from contact with the solder strip when the cam 36 is moved out of contact with said plate. The cam 30 operates in alternation with the cam 36 so that the latter releases its clamping plate when the slide moves toward the clamp and the slide cam releases its plate during a movement in the opposite direction at which time the cam 36 holds the strip during the return movement. The feeding of the slide may be effected in any desiredmanner, for instance by thepitman' '40 pivoted thereto and to the feed cam 41. This feed cam is formed with an extension 42 having a slot 43 extending radially from the axis of the cam and adapted to receive an a-djustable block 44 upon which the pitman is pivoted. This block 44 is clamped in any desired position by means of a nut 45 carried by the bolt 46 extending therefrom as shown by detail in Fig. 10. This permits an adjustment of the length of stroke of the pitman and the feed slide carried thereby. The cam 41'is provided with a shaft 47 over which a sleeve 48 is disposed (Fig. 12), and secured thereon by means of a washer plate 49. The sleeve 48 is provided with a driv ing gear 50 andv a connecting plate 51 which is formed upon one face with a lug 52 adapted to operate within a segmental recess 53 upon the adjacent inner face 54 of the cam 41, these parts being shown in detail in Figs.

-11, 12 and 13. This construction permits a period of rest during the operation of'the cam which is necessary during the cutting ofthe solder strip. The gear 50 ISdIlVQIl by asector 55 mounted at .56 upon-the shaft 57 having a bearing 58 uponthe machine frame. The sector 55 is oscillated by means of the pitman 59 pivoted thereto and to the crank 60 carried by a countershaft 61 mounted in the frame of the machine and having at one end a driving pinion 62 which meshes with a coiiperating pinion 63 upon the main driving shaft 64.

The solder rings are cut from the strip 25 concentric to each other to produce a plurality of rings of different sizes as shown by the diagram in Fig. 19. The smallest ring is first cut and the strips then moved beneath a cutter'for the next larger size, this operation being continued to the capacity of strip.

The shaft 31 by which the clamps of the solder strip slide and clamp are actuated, maybe oscillated by any desired connection, for instance as shown in Figs. 1 and 4 where the arm 33 securedto the shaft 31 is provided with a link 65 pivoted thereto and to a crank arm 66 on the rock shaft 67 which ispivoted in the bearings 68 on the machine frame. The shaft 67 carries a lever arm 69 from which a connecting rod 70 extends to a crank 71 eccentrically mounted at 72 upon the disk 73 carried by the shaft 74. This shaft is mounted in a bearing 75 and provided with a worm gear 76 meshing with a cooperating gear 77 carried by the main driving shaft 64.

The punching 'or cutting action to form the solder rings is elfected by a series of reciprocating upper dies SOeachof similar construction but of successively increasing size.v These dies each comprise an inner punch portion 81 and an outer movable punch 82 -mounted thereon and normally held by the tension spring 83 in contact with .so i

a shoulder 84 upon the punch 81. This with the stationary frame 89 upon which it is mounted. This frame has an inner cut-' ting edge 90 at the periphery of each of the openings therethrough. Beneath thestripper plate and cutter, a dial plate-91 is pivotally supported and provided with a series of apertures 92 of successively increasing size each being provided with a supporting shoulder 93. These apertures correspond in size to the diameter of ring to be cut and retain both the ring and the cap during its travel through the machine. As shown in Fig. 14, the dial plate is provided with four series of these apertures'in order to maintain a continuous operation as will be hereinafter described. Beneath the dial plate, a punch head 94 is mountedfor movement toward and from the said plate. This head is provided with a series of discharge passages 95 by which any excess material may fall after the punching operation. Surrounding each of the apertures is an inner cutting ring 96 which cooperates with the punch 8l,while the outer cutting edge 90 co;'.

. operates. with the punch 82. A

- The head 86, carrying the upper punches, is-carrie'd by a reciprocating plunger 97, extending downward through the machine and connected'by a pivoted pitman 98 with a.

crank 99 upon the main driving shaft 6421s shown by dotted lines in Fig. 4. The. head is also provided with a guide arm 100 adapted to slide in a guide 101 mounted upon the frame of the machine as shown in Figs. 1

and 4.

The dial plate 91 is rotated by means of a depending sleeve 102 which surroundsthe plunger 97 and is provided at its lower end with a cam plate 103 having a series of loo spaced contacts 104 adapted to engage and an oscillating movement by the means drivtraverse the spiral paths 105 carriedfby the ing the sector for the solder strip feed above cam 106 which is mounted upon theeounterdescribed. This shaft is supported in hangshaft 61 before described, as shown in Figs. ers 197 and carries a gear'1'98 which meshes .5 2 and 20. i

to limit the movement of the die away from the head. The die is held in this position by means of the tension spring 169 disposedwithin the recess 170 thereof and bearing against both the head and die (Fig. 17 The releasing plunger 171 is also mounted in the post 167 and is provided with a head 172 to limit its outward movement, While it is held in that .position bymeans of a ten;

sion spring 173 disposed within the post and bearing at its upper end against an adjustable screw 1741 threaded into the post.

'The posts are secured in position upon the head by means of the nuts 17 5. The lower securing die 176 is provided with a convex face 177 to coperatewith the concave face 166 and is mounted in a reciprocating head V 178 which is also capable of oscillatory movement for discharging the completed hemmed cap therefrom. The action of these dies is to compress the solder ring about the periphery of the cap by contact of the opposite dies therewith. The upper die being yieldingly mounted to prevent injury to the article, while the plu'ngers release the caps from the upper dies, leaving them resting upon the lower dies from which they are discharged.

The die head 17 8 is pivotally mounted at 179 the slide block 180 mounted in the vertical way 181 at the delivery side of the frame. ,Beneath this block, the shaft 182 is pivoted.and has secured thereto a cam 183.

Thesliaft is provided at its end with a crank arm 184 connected by a link'185 with an arm of'the bell crank lever 111 above de- I scribed, This connection effects an oscillation of the cam to raise the dies into the 7 -position shown in Fig. 21. The swinging movement of the head 178 for the purpose of discharging the completed cap, shown in F ig.'18, is controlled in the continued move ment of the shaft 182 before and after. the action of the cam in raising and lowering the head, respectively. The head is nor tension spring 186 secured to the pivot 179 and to the slide block at 187 so as. to be curved at 188 to cooperate with a similar face 189 upon the-head to form a guide for the swinging movement. This movement is produced by a lever "190' loosely mounted upon the shaft 182 and connected by a link 191 to a pivoting lug 192 upon the head 17 8. At opposite sides of thelever 190, a strike arm 193 is secured to the shaft 182 and has a portion 191 disposedto engage said lever in the oscillation of theishaft'182 as shown in Fig. 3. With the head in raised position,

as shown in Fig. 21-, anoscillation of the shaft 182 first withdrawslthe cams from beneath the sliding block, permitting its downward movement and the continued travel of this shaft brings the strike arm 193 into contact with the loosely pivoted lever 190, thus moving the latter downward and swinging'the headoutward to place its spring under tension and. deliver the com- .pleted article therefrom (Fig. 4). In the returning or opposite travel of the shaft 182,

the strike arm is first removed from the lever and the spring connection between the head and slide block draws the former into vertical positionand the ciprocation of the parts. In the operation of the machine, the solder strip is fed as described beneath the cutting punches andra series of rings. of different sizes produced. The clamp for' the strip is then released and it is fed forward the distance ofone punch so as to cut the next size ring concentric to the aperture re- :maining after the cutting of the previous ring as illustrated in Fig. 19. This cutting operation also bends up the inner edge of the cam effe'cts the rering and leaves it in the dial plate which is then given. a quarter rotation to bring the rings in positionto receive the caps. These caps are. fed as shown inlFig. 6 and retained in alinement with the rings by the holding arms. The main head is then again reciprocated and the applying dies approach each other during which movement, the holding 'arms are-opened, permitting the cap to drop into place within the ring and the movement of the dies, then bends upward the outer edge of the ring into the positionv shown in Fig. 17, also removing it and the cap from the seat in the dialplate. This plate is then given revolution to bring the caps into alinement with the securing dies which approach each other and bend and hem the ring upon the periphery of the cap as shown in Fig. 18. In the retracting movement of these dies, the lower die is automatically swung outward to deliver the completed article.

, The machine is arranged for a continuous automatic operation and by a proper arr'angement of the size of dies, may produce hemmed capsv of different sizes or of the same size while the movement of the parts is so timed and connected to a main drivan operating cam for said ing shaft as to effect the proper succession of operation in the minimum of time and with the most economical use of the solder owing to the cutting of successive rings concentric to each other.
